Who Is “This Love (Taylor’s Version)” About? Swift’s New Single

Per Vulture, in 2014, when Taylor’s “1989” album and “This Love” were first released, every song had a hidden message in the liner notes in true Taylor fashion. She had previously revealed that “This Love” was the first song she wrote for “1989” shortly after she was finished with the “Red” album. The hidden message in the liner notes reads, “Timing is a funny thing,” and the lyrics hint at a relationship where one party returns to the other.
